How long does 2 lbs of Freon last?

Freon (which is really just a particular brand of refrigerant) lasts forever. It's not like gas in car; it does not get “used up.” You see, your air conditioner's refrigerant system is a “closed/sealed system,” meaning that it does not allow refrigerant to escape in any way.

How many pounds of refrigerant per ton? (2023)

How many pounds of Freon does a R22 hold?

Residential units, when services, leak on average, 3-5 pounds. Average size units hold 5+ pounds.

Is 410A being phased out?

However, the EPA has proposed banning the use of R410-A in new air conditioners and heat pumps by January 1, 2025. As R410-a production gets gradually reduced and phased out, the refrigerant will likely become harder to find and get more expensive.

Why is 410A so expensive?

R410a is actually a blend of two different refrigerants, one of which is called R125. There's currently a world shortage of R125 because there aren't enough plants to produce it. Without enough R125, producers can't make enough R410a to keep up with the increasing demand.

Is R-410A refrigerant being phased out?

Starting in 2023, new HVAC systems will no longer use R-410A. These systems will also be subject to new energy efficiency standards.

What is the pressure of r410 gas in a 1 ton AC unit?

For a 1.5-ton AC, 700 to 900 g of gas is required whereas around 400 to 600 g of gas is required for a 1-ton AC. However, you need to check which gas you're filling as R22 requires 60 to 65 PSI, R32 requires 110 to 120 PSI, and R410A requires 110 to 120 PSI.

The BTU for air conditioners ranges from 5000 to 24000 BTUs and 12000 BTUs is equal to 1 ton.

How much AC capacity per ton?

One ton of air conditioning can remove 12,000 BTUs of air per hour. A four ton unit can move 48, 000 BTUs and so on. Therefore, the more tonnage an AC unit is rated at, the more air it can cool.

How do you calculate pounds of refrigerant?

Divide this amount of heat by the refrigerant's heat transfer rate. If the refrigerant moves, for instance, 170 kj/kg, then: 263,750 / 170 = 1,551 kg. Multiply this weight by 2.2 to convert it to pounds: 1,551 x 2.2 = 3,412 lb.

What is a CFM in HVAC?

Cubic Feet Per Minute (CFM) is a measurement of airflow volume, determined by how many cubic feet of air pass by a stationary point in one minute. Larger homes circulate more air (since there's more space for it to move around), so they will have a higher CFM.

What is 2 tons of refrigeration equivalent to?

When refrigeration or air conditioning equipment is rated for 1 ton of cooling, it means that the equipment should remove heat at a rate of 12,000 Btuh. However, equipment that is removing 12,000 Btu in 30 minutes would have a capacity of 2 tons.

Why is it called a ton of refrigeration?

Before refrigeration air conditioning was invented, cooling was done by saving big blocks of ice. When cooling machines were invented, their capacity was rated by the equivalent amount of ice melted in a day, which is where the term “ton” came from in sizing air conditioning systems.

How many units is tons of refrigeration?

A ton of refrigeration (TR) is a unit of heat extraction capacity of the refrigeration or cooling equipment. Generally, TR is defined as the amount of heat transferred to freeze or melt 1 short ton of ice at 0 deg. C in 24 hours. 1 TR is approximately equal to 12000 BTU or 3024 Kcal/hr of energy/heat load.

What is the old Freon called?

Until 2010, R-22 was the most frequently used refrigerant in air conditioners and heat pumps. Because R-22 causes ozone depletion, the Environmental Protection Agency required manufacturers to phase out its use. In 2015, R-410A became the standard refrigerant used.

Why is R-22 so expensive?

Why is Freon R-22 so expensive? The reality is you are a victim of supply and demand due to the shortage of Freon R-22. You see, nearly 30 years ago the EPA (Environmental Protection Agency) ruled that Freon R-22 should be phased out as it contains ingredients that have been shown to deplete the ozone.

Can Freon go low without a leak?

Refrigerant is not consumed or used up in normal day-to-day operations, but some cars due exhibit a slight loss over time. While some will argue that on the molecular level no system is completely sealed, when your vehicle leaves the factory, its air conditioning is essentially leak free.

Does refrigerant go bad?

That's because refrigerant simply does not go bad or expire. As long as the cylinder or can is fully sealed (no leaks) and the valve is not open or broken, refrigerant will last in its container indefinitely. If intact, the can/cylinder is a sealed unit and will not deplete or leak refrigerant.

Why are old Freon so expensive?


What little Freon is made has become so rare that the prices have skyrocketed. Much of the Freon you can buy today is actually reclaimed, meaning it was extracted from an old system before disposal. Since the supply is so low, but demand still remains fairly high, Freon prices are jaw-dropping.

R-22a is a hydrocarbon refrigerant blend with primary components including flammable substances such as propane and butane. In some cases, it may also contain small amounts of other hydrocarbons or a pine-scented odorant. This refrigerant is a highly flammable, colorless gas that is heavier than air.

Can you add R22 as a liquid or gas?

Pure refrigerants like R22 can be added in liquid or vapor states. If adding liquid into the suction like, throttle it in slowly to avoid slugging the compressor or diluting and washing out the compressor oil. After the charge has been set, avoid installing the gauges as part of regular service.
